Nokia NRS II study guide
Nokia NRS II · Work through your exam, one topic at a time.
NRS II is the second tier of Nokia's routing and switching certification path, aimed at network engineers who design, deploy, and operate IP/MPLS networks built on Nokia service router platforms. Nokia describes its industry-recognized certification programs as a way to "build your technical expertise and enhance your professional standing," and the IP networks solution area is framed around building "scalable, secure, and adaptive networks." The exam is organized into four equally weighted domains: IP networks; IP routing, switching and aggregation; IP network automation; and IP network security. The Nokia NRS II study guide has 5 sections and about 1,675 words.
01IP networks
NRS II tests your command of IPv4 and IPv6 addressing and forwarding as implemented on Nokia SR OS: how a physical port becomes a router interface, how addresses and subnets are applied, and how packets are resolved and forwarded. Expect questions on subnetting, point-to-point addressing, IPv6 neighbor discovery, MTU handling and basic services such as DHCP and DNS.
358 words, about 2 min02IP routing
This domain covers how SR OS builds and selects routes: IGPs (OSPF, IS-IS), BGP, route preference, ECMP and route policy. The exam expects you to know why one route beats another, how areas/levels constrain topology, and how policy changes what is imported or exported.
347 words, about 2 min03Switching and aggregation
This domain tests Layer 2 transport and the service constructs Nokia uses to aggregate it: VLANs, STP variants, LAG/MC-LAG, and Ethernet services (Epipe, VPLS, IES, VPRN) built from SAPs and SDPs. 802.1Q tags carry a VLAN ID; QinQ (802.1ad) stacks an outer S-VLAN for provider aggregation.
335 words, about 2 min04IP network automation
The exam tests model-driven management of SR OS: how configuration and state are exposed through YANG, and how operators automate with NETCONF, gNMI, SNMP and Python instead of the CLI. Expect questions on datastores, transactions, telemetry and Nokia NSP.
306 words, about 2 min05IP network security
This domain covers protecting the router and the services it delivers: filter policies, CPM protection, management access control, routing-protocol hardening, and encryption at Layer 2 and Layer 3. Filter policies ( config filter ip-filter , ipv6-filter , mac-filter ) are applied to SAPs, network interfaces or CPM.
